Fusion HCI with SAN HBAs for Fusion Access

Fusion Access enables customers to use their existing SAN Block-Storage on OpenShift with our gpfs filesystem, which has significant advantages over block based CSI drivers!
Unfortunately, this is only supported on Fusion SDS, as Fusion HCI does not support SAN HBA.

The Idea:
IBM should support an RPQ based proccess, that allows customers to add FC-HBAs to their Dell based Fusion HCIs.
The customer can add provide their own Qlogic or Emulex HBAs, that will be installed by an IBM SSR.
The HBA drivers should be already included in RH coreOS.
IBM Fusion supports the IO stack top down to the FC-HBA.
The customer needs to support masking, zoning, multipathing and all SAN based configurations and issues, as those outside of Fusion HCI.
The idea is to use this setup with Fusion Access. The use of block CSI drivers should be avoided and limited to as few LUNs as possible.

    This is a critical requirement we must meet if we want to advance the strategy of moving VMware workloads to OpenShift Virtualization. Most customers have significantly higher storage capacity needs than our current storage nodes can provide. Adding nodes solely to satisfy capacity demands — without an actual need for additional compute — would unnecessarily increase Fusion costs (both Fusion software and OCP licenses), ultimately undermining the TCO value proposition.
